What's up with Pricing? I had been looking to purchase these shoes for several days now and was going to order from the Olukai website. I then got an email from Backcountry (from whom I've purchased from in the past). I looked for the shoes, and viola...there they were...on sale! or so I thought. Of the roughly 30+ color/size combinations, only 4 obscure sizes are actually on sale! The others are the same (original) price as on the olukai website. Seems kind a bait and switch to me.
